Oil above $100. Gas prices up 70%. Every crisis has a different trigger—and the same vulnerability. Europe must become the world's first Electro-Continent.

    Nah, if you assume 6-12h of storage needed it’s close to break even. I’d say if prices of batteries get halved again, it’s solved

      Can we do some calculations for worst case, ie winter week with clouds at best? How much does a single household consume when using heat pumps for warming? That would be at least 30kWh per day just for heating. Let’s round it to 40kWh pet day which makes 280kWh per week. Shall we add an EV car into equation? 140kWh? We are at 420kWh per week you might need to back up with batteries. Now multiply this number with millions of households. Or simply take a look at electric energy consumption in your country during winter days (when many don’t even have heat pumps and EVs) and you think there is enough batteries around and is simply a matter of price? Good luck with that. Wind and hydro would help to some extent, though.

        When I said break even, I meant financial feasibility. Point is you can invest in solar power plus 12h of storage and this makes financial sense.

        As for winter periods, noone expect solar to magically work in winter. Point is to reduce dependency on fossil and this can be achieved. You’d still expect strategic energy reserves and winter power to be delivered through fossil, due to avaliabliy and good energy density.

        You could substitute fossil with wind power during winter, but that still requires storage.
